The Wireless bracelets and Bluetooth Watches have enough sensors to not only measure our heartbeat but sometimes even detect irregular blood oxygen. It’s pretty amazing that now these are even available in something as small as a ring from Fitiger. Being able to make sense of the data via wearables is completely more important than just having access to it, which is why this fashionable smart ring gives wearers a nudge in the right direction in living healthily.
Almost all smartwatches and fitness trackers these days show data such as heart rate, sleep duration and many more，which can already indicate when there’s something wrong with your body, but they can’t really give you a deeper and more holistic view of your health. The Fitiger Ring, in contrast, not only measures those same metabolic biomarkers, such as heart rate variability, temperature, and sleep. it also interprets them into something that’s easier to understand and act on.
